Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563226, here are decompositions:
- 5 + 31563221 = 31563226
- 17 + 31563209 = 31563226
- 89 + 31563137 = 31563226
- 137 + 31563089 = 31563226
- 197 + 31563029 = 31563226
- 239 + 31562987 = 31563226
- 449 + 31562777 = 31563226
- 599 + 31562627 = 31563226
Showing the first eight; more decompositions exist.
